Use Of Florpyrauxifen-Benzyl In Non-Flooded Rice Production Systems, Hannah Wright, Jason K. Norsworthy, Trenton L. Roberts, Robert C. Scott, Jarrod T. Hardke, Edward E. Gbur

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

The lack of a flood on rice (Oryza sativa) levees and in furrow-irrigated rice creates a favorable environment for terrestrial weeds like Palmer amaranth (Amaranthus palmeri S. Wats) to emerge and quickly overtake the crop for a longer portion of the year than in flooded rice culture. Florpyrauxifen-benzyl is a new auxin herbicide labeled for use in rice that has activity on both grasses and broadleaf weeds, as well as certain sedges. Field experiments were conducted to determine the efficacy of florpyrauxifen-benzyl in a non-flooded environment. Experiments were conducted in 2017 and 2018 at the Lon Mann …


Critical Period Of Palmer Amaranth Removal And Effects Of Late Season Herbicide Applications On Palmer Amaranth Seed Production, José Henrique Scarparo De Sanctis Nov 2020

Critical Period Of Palmer Amaranth Removal And Effects Of Late Season Herbicide Applications On Palmer Amaranth Seed Production, José Henrique Scarparo De Sanctis

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Palmer amaranth is the most troublesome weed in agronomic crops in United States. Therefore, an integrated weed management approach is necessary to successfully manage this weed. The use of residual pre-emergence (PRE) herbicide applied at planting can delays the is one of the critical time of Palmer amaranth removal (CTPAR) giving farmers more time to prepare the weed control tactics and to preventing an unacceptable yield loss in soybean due to Palmer amaranth competition. Field experiments were conducted in 2018 and 2019 in a grower’s field infested with GR Palmer amaranth near Carleton, Nebraska, to determine the CTPAR in soybean …

Response Of Grain Sorghum To Low Rates Of Glufosinate And Nicosulfuron, Hunter Bowman, L. Barber, Jason K. Norsworthy, Trenton L. Roberts, Jason Kelley, Edward E. Gbur

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Previous research has shown that glufosinate and nicosulfuron at low rates can cause yield loss to grain sorghum. However, research has not been conducted to pinpoint the growth stage at which these herbicides are most injurious to grain sorghum. Therefore, field tests were conducted in 2016 and 2017 to determine the most sensitive growth stage for grain sorghum exposure to both glufosinate and nicosulfuron. Field test were designed with factor A being the herbicide applied (glufosinate or nicosulfuron). Factor B consisted of timing of herbicide application including V3, V8, flagleaf, heading, and soft dough stages. Factor C was glufosinate or …

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Benzobicyclon has shown varying results in controlling weedy rice, including those with imidazolinone (IMI) resistance. Tolerance to benzobicyclon in cultivated japonica rice, but not indica or aus-like cultivars, is conferred by a fully functional HPPD Inhibitor Sensitive 1 (HIS1) gene. Herein, a diagnostic Kompetitive Allele Specific PCR (KASP) assay was developed to predict the HIS1 genotype of weedy rice plants from 37 accessions and correlated to their response to benzobicyclon in the field. Two-thirds of the 693 weedy rice plants screened were tolerant to benzobicyclon (371 g ai ha−1, SC formulation) at 30 days after treatment (DAT). …

15N Fertilizer Recovery And Partitioning By Cover Crops Under Greenhouse Conditions, Kelsey L.H. Grueb, Trenton L. Roberts

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Cover crops have the potential to decrease residual-nitrogen (N) losses from agricultural soils by capturing and storing excess N between cash crops. This study was established to assess the effect of cover crop species and N rate on the accumulation and partitioning of biomass and 15N fertilizer by cover crops produced under controlled environmental conditions. Cereal rye (Secale cereale) and tillage radish (Raphanus sativus) cover crops were grown in monoculture and in a blend under greenhouse conditions in two soils. Urea enriched with 15N (3.0 atom %) was applied to cover crops at rates …

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Global climate change, specifically rising temperature, can alter the molecular physiology of weedy plants. These changes affect herbicide efficacy and weed management. This research aimed to investigate the combined effect of heat stress (HS) and sublethal doses of herbicides (four active ingredients) on adaptive gene expression and efficacy of herbicide on Echinochloa colona (L.) Link (junglerice). Three factors were evaluated; factor A was E. colona generation (G0-original population from susceptible standard; G1 and G2 were progenies of recurrent selection), factor B was herbicide treatment (florpyrauxifen-benzyl, glufosinate-ammonium, imazethapyr, quinclorac and nontreated check) and factor C was HS (30 and 45 °C). …

Potential effectiveness of harvest weed seed control (HWSC) systems depends upon seed shatter of the target weed species at crop maturity, enabling its collection and processing at crop harvest. However, seed retention likely is influenced by agroecological and environmental factors. In 2016 and 2017, we assessed seed-shatter phenology in 13 economically important broadleaf weed species in soybean [Glycine max (L.) Merr.] from crop physiological maturity to 4 wk after physiological maturity at multiple sites spread across 14 states in the southern, northern, and mid-Atlantic United States. Greater proportions of seeds were retained by weeds in southern latitudes and shatter rate …
